Programatically Access Statistics from 3G Mifi/Access Point!!

By Menelaos Bakopoulos • Scripts • 1

Specifically I’m going to talk about the Huawei MIFI (Mobile 3G Wifi) E585 though these could be applied to another access point/ mifi. You will need the web debugger FIDDLER (a http request sniffer).

So, probably your MIFI/access point is configured with IP address 192.168.1.1 .

If there are pages that display the statistics (such as those on the E858) there is a chance the information can be accessed through a .php or other dynamic page.

On the E858, accessing http://192.168.1.1/ displays the current total download/upload and flux for the current session. (pictures coming later).

However, if you want to check more analytical statistics such as total usage you have to log on. Fortunately, if the data screen uses a JQuery (or javascript ajax script)  fiddler can be used to sniff and discover the data source (post me a line for more instructions).

In the case of E858, all statistics are accessible through http://192.168.1.1/ipad.cgi which includes current bit rate, total number of connected devices, DNS, etc,  without requiring http authentication.

Below is a quick proof of concept which parses the total usage (in gigabytes) and sends an e-mail when over a threshold.  It’s a proof of concept – not an actual robust app 😛 (feel free to extend though) .

The parsing of ipad.cgi for the E858 or other data sources for other devices can  be used to interesting tools and widgets not provided initially by the company software (if circumstances allow). In my case I plan to build a windows taskbar monitor to display total connected users, total data consumption, and real time info from my pc without logging into the MIFI.

Hope it helps!
